FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 257,654, dated May 9, 1862. i

Application tiled February l, 1882. (No model.)

` and theletters of reference markedv thereon, to

be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figures l and 2 vertical central sections, showing different plugs; Fig. 3, a modification. This invention relates to an improvement in distributers for that class ctl tire-extinguishers in which a line of pipe is led to the apartment to be protected and there fitted with a distribnter, which, when the water is let on, will distribute the waterinthe form' of spray to extinguish the tire that may have accidentally occurred in the apartment, the object ot' the invention being the construction ot' a distributer which will throw the water over a larger space than the common perforated rose, and which may also be pendent from the ceiling, and thereby distribute the Water over a very large apartment; andthe invention consists in a disk attached to the discharge-nozzle a little distance from the discharge, the plane of the disk being at right angles to the line of discharge, and the disk constructed with adange projecting toward the discharge and perforated', whereby thewater iiowing with force through the nozzle will first strike the disk, their spread radially in all directions, will be discharged through the perforationsin the rim, and turned upward over the rim, will also throw an unbroken thin sheet of water ot' umbrella-like form, of which the distributer forms the center; and,also, in thearrangement ofthe plug whereby this, distribution ot' Water is facilitated, as more fully hereinafter described.

A represents the nozzle, to which the water is led through the eonductingpipes in the usual manner, and arranged at the pointwhere the 'distribution is to be made. Bis a cup shaped disk, preferably dat bottom, arranged in a-plane at substantially right angles to the water-way or'discharge and alittle distance from the discharge-opening. Itis attached to b of the disk turns toward the nozzle and y stands preferably at an angle of about thirty degrees to the plane of the disk-that is, eX- pandingtoward the nozzle. The rim is smooth upon its inner surface, but with numerous perforations, d, made therein. Then, when the water is let on, it passes from the nozzle and strikes with force upon the bottom of the disk, and there spreads in all directions, striking the riln. A portion passes out through the perforations in theform of spray, as it does in the usual perforated rose. The balance is turned upward by the inner surface of the rimand forced over the edge of that rim in a thin umbrella-like sheet, of which the distributer forms the center, as indicated in broken lines, Fig. 1. This sheet will be thin, and will be thrown at a great distance, breaking eventually into the form of spray, and thus this sheet, combined with the spray directed through the perforations, will distribute to all parts of the apartment. Other perforations-may be made in the bottom of the distributer.

Instead ot' making the distributer flat-bottomed, as seen in Fig. l, itmaybe 'concave shape,

as seen in Fig. 3-that is, shaped similar to the forced down upon the bottom of the distrib-l uter directly in line of the discharge, so that the water will strike upon this conical shape and be spread in all directions more easily and readily than if it strike'upon the flat bottom.

Instead of soldering the plug in the end of the nozzle, it may be secured by solder over the end of the spindle, as indicated at e, which attaches thespindle to the distributer. In this case the distributer and its connection must be of sufficient strength to support the plug against the pressure of water. Another advantage of this last construction is that the plug is held in place by the distributer, which is screwed to the end ot' the nozzle. Hence the nozzle may be unscrewed and the plug removed or examined at any time without discharge upon which the water will strike and be thereby spread, as such, I am aware, is not new.

I claim- 1. llhe distributcr consisting of the cupshaped disk attached to the nozzle and arranged in a plane at substantially right angles to the discharge anda short distance therefrom, the rim ot' the said cup perforated, substantially as described.

2. The distributer consisting of thecupshaped disk attached to the nozzle and arranged in a plane at substantially right angles to the discharge anda short distance therefrom, the rim ot' the said cup perforated, with a conical plug to close thc nozzle, secured by a fusible connection, the spindle ot' the plug eX- tending through the bottom of the distributer, substantiall y as and for the purpose described.

3. The distributer consisting of the cupshaped disk attached to the nozzle and arranged in a plane at substantially right angles tothe discharge and a short distance therefrom, the rim ot' the said cup perforated, with a plug to close the nozzle, its spindle extending through the distributer and secured by a fusible connection between the spindle and the distributor, substantially as described.
